[Mandibular condyle tumors (author's transl)]. / Les tumeurs du condyle mandibulaire.

The must frequently observed mandibular condyle tumors are benign in nature, followed by metastases; primary malignant tumors are very rarely encountered, following a review of the clinical and radiographic characteristics of all types of tumors that occur, three cases of condylar metastases are described. Treatment of primary tumors is exclusively surgical, that of secondary lesions being palliative because of the often poor prognosis related to the primary tumor.

[Early radiologic signs of Burkitt's lymphoma]. / Signes radiologiques précoces d'un lymphome de Burkitt.

This paper relates a case of Burkitt lymphoma, whose initial presentation was a deep-bite malformation, that accentuated within a month. Orthodontic consultation referred this 8 years old boy to hospital, where diagnosis was ascertained. The authors discuss radiographs that have been taken before and during the installation of the clinical symptomatology. They point out the main radiographic signs encountered with maxilla involvement in Burkitt lymphoma.

[Reconstruction of the loss of substance of the lower lip. The "running stairstep" technic]. / Reconstructions des pertes de substance de la lèvre inférieure. La technique des "marches d'escalier".

Reconstruction of near the totality of the lower lip after oncological resection or traumatic amputation, is a very challenging problem. The "step technique", introduced by Johanson, allows a good repair of the amputated lip, regarding amplitude, colour and function. The design of the flaps is recalled; and the authors present two cases which demonstrate the good result obtained with this simple but reliable method.

[Mandibular osteitis and tertiary syphilis]. / Ostéite mandibulaire et syphilis tertiaire.

The authors report the case of a 65 years old man, who suffered from an osteitis, involving the mandible. Within a few months, and despite of a well established treatment, sequestration occurred following a pathologic fracture. No specific germ was encountered after several laboratory examinations. The discovery of a primary syphilis forty years ago, confrontation of clinic and paraclinic data, suggested the actual osteitis could be a complication of tertiary syphilis. A specific treatment was started, and the situation improved progressively. After five months of treatment, mandibular reconstruction was decided. Diagnostic arguments are discussed, and the case is compared with those, not numerous, reported in the literature.

[Myocutaneous island flap of the lower trapezius. Its value in facial oncology practice]. / Lambeau myocutané de trapèze inférieur en îlot. Intérêt en pratique carcinologique faciale.

Among the numerous musculo-cutaneous flaps, the lower trapezius island appears an interesting procedure for punctual indications. The authors report their experience in utilisation of this flap for reconstruction of defects in auricular area, and in the buccal cavity. They point out some practical problems encountered when raising the flap.

Relatedness of three species of "false neisseriae," Neisseria caviae, Neisseria cuniculi, and Neisseria ovis, by DNA-DNA hybridizations and fatty acid analysis.

DNA-DNA hybridization was used to determine the levels of genomic relatedness of the three species of "false neisseriae," Neisseria caviae, Neisseria cuniculi, and Neisseria ovis. The reference strains of these species exhibited high levels of intraspecies relatedness (93 to 100% for N. caviae, 79 to 100% for N. cuniculi, and 68 to 100% for N. ovis) but low levels of interspecific relatedness (less than 34%) to each other and to various species belonging to the beta subclass of the Proteobacteria (Kingella kingae, Neisseria gonorrhoeae, Neisseria meningitidis, and Oligella urethralis) or to the gamma subclass (Branhamella catarrhalis, Kingella indologenes, Moraxella atlantae, Moraxella bovis, Moraxella lacunata subsp. lacunata, Moraxella lacunata subsp. liquefaciens, Moraxella nonliquefaciens, Moraxella osloensis, and Moraxella phenylpyruvica). However, the levels of DNA-DNA hybridization for the three species of "false neisseriae" were significantly higher with the species belonging to the gamma subclass (average, 13.7%) than with the species belonging to the beta subclass (average, 4.5%). These data suggest that N. caviae, N. cuniculi, and N. ovis are three separate genomic species in the gamma subclass. An ascendant hierarchical classification based only on fatty acid profiles distinguished four main classes containing (i) most of the "classical moraxellae," the "false neisseriae," and B. catarrhalis, (ii) only Acinetobacter spp., (iii) M. nonliquefaciens and "misnamed moraxellae" (M. atlantae, M. osloensis, and M. phenylpyruvica), and (iv) the "true neisseriae," the three Kingella species, and O. urethralis. Fatty acids that distinguish these four classes were identified. The fatty acid profiles of the two strains of Psychrobacter immobilis which we studied are not very similar to the profiles of the other taxa. Our results support the hypothesis that the three species of "false neisseriae," B. catarrhalis, the "classical moraxellae," and Acinetobacter spp. should be included in the same family.

Screening of the C677T mutation on the methylenetetrahydrofolate reductase gene in French patients with neural tube defects.

We report the analysis of the distribution of the C677T mutation on the methylenetetrahydrofolate reductase (MTHFR) gene in prenatally diagnosed neural tube defects (NTD) cases and controls. In contrast to previous reports, we found the same distribution in fetuses with NTD and controls, which suggests that the MTHFR C677T mutation cannot be regarded as a genetic risk factor for NTD.

Eficacia y seguridad de la esclerosis con espuma de las várices de miembros inferiores / Effectiveness and safety of foam esclerosis of varix of lower limbs

Objetivos: documentar los resultados de los primeros 285 pacientes tratados con esclerosis con polidocanol, en forma de espuma y sin el empleo de ultrasonido como guía, por presentar várices de miembros inferiores. Métodos: Se realizó un estudio prospectivo, monocéntrico y controlado que incluyó los primeros 285 pacientes que asistieron a una consulta de flebología por presentar várices tronculares o microvárices y a los cuales se les realizó esclerosis de sus lesiones con polidocanol en forma de espuma sin guía por medio del ultrasonido. Se evaluaron un grupo de variables demográficas y se cuantificó la efectividad, el número y tipo de complicaciones y la satisfacción del paciente a los 30 días de concluido el tratamiento. Resultados: Se logró una efectividad del 82 por ciento con una sola sesión de tratamiento que se elevó al 94 por ciento con dos sesiones. Las principales complicaciones fueron el dolor (33,6 por ciento) y el mapeo (12,9 por ciento) y el 90 por ciento de los pacientes se mostró satisfecho con el tratamiento. Conclusiones: la esclerosis con espuma de los trancos venosos y las microvárices fue efectiva, segura y logró un alto nivel de satisfacción de los pacientes.

Objetive: To verify results obtained from the first 285 patients presenting with sclerosis and lower limbs varix, treated using Polidocanol in foam way, and without ultrasound guide. Methods: A prospective, monocentric and controlled study was carried out including the first 285 patients seen in Phlebology consulting room presenting with truncus and microvarix underwent sclerosis of their lesions usisng Polidocanol in a foam way without ultrasound guide. We assessed a group of demographic variables and also we quantify effectiveness, number and type of complications as wll as the satisfaction of patient after 30 days of treatment. Results: We achieved a 82 percent efectiveness with a single session of treatment, which increased to 94 percent with two sessions. Main complications included pain (33,6 percent) and mapping (12,9 percent), and 90 percent of patients were satisfied with treatment. Conclusions: Sclerosis in a foam way of venous trunks and microvarix was effective, safe and achieves a high level of satisfaction in patients.
